SIIUBBING DEVICE.

Application filed November 23, 1926. Serial No. 150.175.

This invention relates to suubbing devices a ndmorc particularly to a type useful in connection with yarn winding apparatus known in the textile industry as beam warpers. In the operation of such apparatus, warp yarns are drawn from individual bobbins or cones, grouped, and distributed as a horizontal sheet for winding upon a beam maintained by its own weight, in running contact with a driving roller; By virtue of being thus floatingly" supportechthe beam has a tendency to bob up and down relative to the driving roller. especially when light at the beginning of a new winding and be fore suificient yarn has accumulated thereon to render it positionally stable.

The objects of my invention are to overcome the above difliculty, and to provide a reliable snubbing means capable of dampening or absorbing spasmodic bobbing move ments of the winding beam so that warping apparatus of the character referred to can be safely operated at much higher speeds than heretofore possible.

In the drawings herewith Fig. I is a side elevation of a beam warping apparatus equipped with my improved snubbing devices; and,

Fig. II is an illustration on a larger scale than the preceding, showing one of the snubbing devices with portions thereof in section for better disclosure of certain important features novel in its construction.

lVith more detailed reference to these illustrations, 1O designates a support or creel for a multiplicity of yarn cones or bobbins 11 providing the individual yarns or warp ends W, which are directed by a guide 12 to a reed 13 supported crosswise between the side frames of the beam warper, comprehensively designated 14:, and uniformly distributed by said reed in a. transverse direction to form a horizontal sheet. The yarns or warp ends W are next passed about a group of tension rollers 15, thence through a second spacing reed 16 and over a final guide roller 17, enroute to the winding beam shown at 18. This winding beam 18 is fioatingly hung to the frame of the beam warper by arms 19 for maintenance by its own Weight, in running contact with a continually revolving driving roller 20, with capacity, as the yarn accumulates thereon, to move away from said driving roller.

To offset the tendency of the winding beam 18 to bob up'and down relative to the driving roller 20 incidental to winding of the warps, I provide snubbing means having the form of links 21 with their ends pivotally connected respectively at 22 and 23 to the arms 19 and fixed anchorages 2 1 at opposite sides of thebea'm warper 1 1. As shown in Fig. I], the links 21 comprise two overlapping bar sections 25, 26, whereof the lastmem tioned is equipped, at intervals along its length, with laterally projecting studs 27 that extend through a longitudinal slot 28 in the section 25. The studs 27 are headed as at 29 and surrounded by helical springs 30 which are in compression between washers 31 and 82 respectively engaging the heads 29 and the outer face of the slotted bar 25. As a consequence of this arrangement, the snubhing links 21 are accorded capacity for shortening or lengthening in responding to the movements of the beam 18; but such action is subject to the frictional restraint imposed under combined action of the several compression springs 30 as a consequence of which, it will be seen that bobbing of the warp beam 18 is effectively prevented. This is not only advantageous in enabling the apparatus to be run at very high speeds, but offsets the possibility of injury to the yarns due to surface slippage as between the warp beam 18 and its driving roller 20. i

Although I have described my invention as particularly useful in association with textile apparatus, the same may obviously be employed, with advantages equal to those hcreinbefore pointed out, in other connections where snubbing is essential in restricting the action of floating or movably suspended or supported parts.

Having thus described my invention, I claim: p

1. A snubbing device for beam warpers adapted to hold the winding beam to the the latter in sliding frictional contact with its fellow.

3. A .snubbing device for beam warpers adaptedto hold the winding beam to the tiona-lly-engaging longitudinally-sliding sec tions for capacity to lengthen and shorten in yieldingly restraining said winding beam against bobbing relative to the driving roller.

5. In beam warping apparatus wherein a winding beam is suspended by pivoted supporting arms and rests by its own weight in running contact with a driving roller, snubbing dev ces having the form of links adapted for pivotal connection at one end to the arms aforesaid and at the other to fixed anchorages, said snnbbing devices being composed of frictionally-engaging longitudinally-sliding sections for capacity to shorten or lengthen in yieldingly restraii'iing said winding beam against bobbing relative to the driving roller.

In testimony whereof. I have hereunto signed my'name at Gastonia, N. (1, this 12th day of November, 1926.
